Maybe someone can help me with my Geier relatives. My great great grandfather George Geier was born in Alsace - Lorraine in 1816. He married Mary Rouft from Wurtemberg, Germany and immigrated to the US although I don't know when. However, their last child born in Alsace was in 1851 and this was my great grandfather Michael Geier, and they were living in Cass County, Indiana in the 1860 census. George's citizenship papers are found in the Logansport, Indiana clerk's office in the Index to Citizenship Papers, Cass County, Indiana 1837-1910.
Perhaps someone can find out more about George Geier & Mary Rouft and link them to Franz Karl Geier.
